1982-49-6 Usage
Chemical Properties
Colorless or white crystalline solid or powder.
Odorless. Commercial product is available as an emulsifi-
able concentrate.
Uses
Selective preemergence herbicide used to control annual weed grasses and prevent
growth of crabgrass, foxtail and barnyard grass in turf, cereals and other food crops.
General Description
Siduron is a pre-emergence and post emergence phenylurea herbicide used for the control of annual grass weeds. Its mode of action involves the inhibition of photosynthesis.
Agricultural Uses
Herbicide: A pre-emergence herbicide used to control annual grasses, e.g., crabgrass, foxtail, and barnyard grass. Used on newly seeded or established turf and lawn grasses and as pre-emergence treatment to bare soil following spring seeding. Not listed for use in EU countries. Registered for use in the U.S.
Trade name
GREENFIELD?; GRO-TONE?[C]; H-1318?; TREY?; TUPERSAN?
Potential Exposure
A phenyl urea preemergence herbicide
used to control annual grasses (e. g., crabgrass, foxtail, and
barnyard grass) and on newly seeded or established turf
and lawn grasses and as bare soil treatment following
spring seeding.
Environmental Fate
Soil. A fungus and two Pseudomonas spp. isolated from soil degraded siduron to form
the major metabolites: 1-(4-hydroxy-2-methylcyclohexyl)-3-(p-hydroxyphenyl)urea, 1-(4-
hydroxy-2-methylcyclohexyl)-3-phenylurea and 1-(4-hydroxyphenyl)-3-(2-methycyclohexyl)urea (Belasco and Langsdorf, 1969).
Plant. After 8 days following absorption in barley plants, no metabolites were detected
(Splittstoesser and Hopen, 1968).

Waste Disposal
Incinerate in a unit with efflu-
ent gas scrubbing. Containers must be disposed of properly
by following package label directions or by contacting your
local or federal environmental control agency, or by
contacting your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 1982-49-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1982-49:
(6*1)+(5*9)+(4*8)+(3*2)+(2*4)+(1*9)=106
106 % 10 = 6
So 1982-49-6 is a valid CAS Registry Number.

A novel synthesis of isocyanates and ureas via β-elimination of haloform
Braverman,Cherkinsky,Kedrova,Reiselman
, p. 3235 - 3238 (2007/10/03)
A novel synthesis of isocyanates via base-induced β-elimination of haloform from N-monosubstituted trihaloacetamides is described. The rate of reaction exhibits a strong dependence on the nature of the trihalomethyl group. Thus, while the reaction of tribromoacetamides proceeds at room temperature and the reaction of trichloroacetamides requires heating in polar solvents, no reaction could be observed for any of the corresponding trifluoro derivatives. This novel β-elimination of haloform from stable and readily available trihaloacetamides was applied to a 'one-pot' synthesis of ureas which avoids the use of phosgene and isolation of isocyanates.
